MARK CONNOR, OF NEW BRIGHTON, PENNSYLVANIA.

AUTOMATIC OPERATING FLUSH-TANK FOR CLOSETS.

SPECIFICATION forming part of Letters Patent No. 743,618, dated November10, 1903.

Application filed June 28, 1900.

To all whom it may concern:

Be it known that I, MARK CONNOR, a subject of the Queen of GreatBritain, residing at New Brighton P. 0., in the county of Beaver andState of Pennsylvania, have invented certain new and useful Improvementsin Automatic Flush-Tanks for Closets; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing bad to the accompanying drawing, which forms a part of thisspecification.

My invention relates to an improved automatic-operating flush-tank forclosets; and it consists in certain details of construction andcombination of parts, as will be fully described hereinafter. I

In the accompanying drawing the-figure is a side sectional elevation ofa tank and automatic-operating siphon for flushing closets, the samebeing constructed and arranged in accordance with my invention.

To construct a flush-tank in accordance with my invention, I provide. atank 1 of a suitable size and form of construction and connect to thebottom of the same a pipe 2, leading to the closet. Attached to orforming a part of this pipe'2 is a water seal con? sisting of an insideshell 6, having an open top, and an outside shell 5, closed at the topand joined at the base to the outlet-pipe 2. Entering through the top ofthese two shells 5 and 6, forming the seal, is a pipe 7, which extendsupward and is connected to an enlarged elbow 8, provided with anintegral downwardly-extending pipe 9, which terminates a short distanceabove the bottom of the tank. A supply-pipe 3, provided with a valve orcook at, is provided to furnish a supply of water to the tank..

In operation the water-supply pipe 3 fills the tank with water to thelevel indicated Serial No. 21,946. (No modeld upon the drawing, andafter reaching this level the water entering the top of the tube 7 formsa siphon which will quickly exhaust the water from the tank until thecolumn of water is broken at the lower end of the pipe 9. The tank 1 isagain slowly filled with water from the supply-pipe 3 and again emptiedwhen it has reached the level above mentioned, thereby producing anautomatic-operated flush for closets.

Having fully described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is

In a device of the type set forth, the combination with a tank of asupply-pipe therefor, a drain-pipe secured to the bottom of said tank,awater seal mounted on said drain-pipe within the tank, said sealcomprising an outer closed shell secured to the base of the drainpipeand having an opening in the upper end thereof to receive a pipe, aninner smaller shell provided with an open top arranged within said outershell, a vertical pipe extending through said outer shell and into thesmaller shell, flanges formed on said pipe near each end thereof, thelower flange resting on the outer shell and the upper flange supportingan elbow, said elbow having an enlarged upper end provided with anopening to receive the upper end of said flanged pipe, and adownwardlyextendingpipe integral with the other end of said elbow andextending to a short distance of the bottom of the tank, substantiallyas described.

In testimony whereof I have hereunto aftixed my signature in thepresence of two subscribing witnesses.

MARK CONNOR.
